An upper level low pressure system centered across the southern plains became nearly stationary through the week of August 19th. This setup allowed for deep tropical moisture to advance northward from the Gulf of Mexico. Small perturbations rounded the back side of this feature and resulted in deep lift needed for widespread showers and thunderstorms across portions of the region. The result was some flooding reports where thunderstorm activity trained over the same general area.
